Haven't uploaded on a while (it was only 2 weeks ago but anyway), so here's a 9K52 Luna-M because yeah.

Description

The 9K52 Luna-M (English: moon, NATO reporting name FROG-7) is a Soviet short-range artillery rocket system which fires unguided and spin-stabilized 9M21 rockets, the 9M21 is a solid fuel rocket with four off-angle vernier chambers immediately behind the warhead section. When the main engine section ignites, the verniers activate to start spinning the rocket to improve stability and accuracy. The rocket is mounted on a transporter erector launcher (TEL) designated 9P113. Based on the ZIL-135LM 8x8 truck, it features a large hydraulic crane to allow faster reloading. The Luna was extensively deployed throughout some Soviet satellite states and it has been widely exported and is now in the possession of a large number of countries.

In this SimplePlanes version, well it's a neat little replica with most of it's functions recreated, it had a working 9M21B ground-to-ground rocket with the cool spinny rockety things, working crane (idk what you'd do with it but hey), and some animation for the launcher rack (animation as in, that one wheel valve spins when the launcher is elevated), it also had an interior cabin, working steering wheel, some basic gauges, and rear wheel steering.

Vernier chambers spinning the rocket for a few milliseconds.

Rocket launch procedure

1. Stop the vehicle
2. Activate AG1
3. Elevate launcher, the max range of the missile is about 65-70km so each bar on the VTOL slider adds about 21-23km of range, I'd suggest getting within 40-35km of the target as it's hard to aim precisely that far out.
4. Launch rocket by pressing Alt or FireWeapons button
